Castle Bloody
Orkney Islands, United Kingdom
Castle Bloody is a prehistoric feature on the island of Shapinsay, Orkney, Scotland. Hogan observes that while the feature is marked as a chambered mound on the UK Ordnance Survey map, the structure is more properly and specifically classified as a souterrain or earth house. Slightly to the north is located the ruined historic Linton Chapel. It is protected as a scheduled monument.
